适用范围
The present document states the minimum requirements for equipment to be used for generation@ transmission and reception of Digital Selective Calling (DSC) for use on board ships. DSC is intended to be used in the Medium Frequency (MF)@ High Frequency (HF) and Very High Frequency (VHF) bands of the Maritime Mobile Service (MMS)@ for distress@ urgency and safety communication and general communications. The present document is part 1 of a multi-part deliverable that covers the requirements to be fulfilled by: ? DSC equipment integrated with a transmitter and/or a receiver; ? DSC equipment not integrated with a transmitter and/or a receiver. These requirements include the relevant provisions of the ITU Radio Regulations and Recommendations ITU-R M.493-15@ M.541-10@ M.689-3 and M.1082-1@ the International Convention for the Safety Of Life At Sea (SOLAS)@ and the relevant resolutions of the International Maritime Organization (IMO). Equipment for generation@ transmission and reception of DSC designed according to the following equipment classes: ? Class A: includes all the facilities defined in annex 1 of Recommendation ITU-R M.493-15 and complies with the IMO Global Maritime Distress and Safety System (GMDSS) carriage requirements for MF/HF installations and/or VHF installations. ? Class D: provides minimum facilities for VHF DSC distress@ urgency and safety as well as routine calling and reception as recommended by IMO MSC/Circ.803 for non-SOLAS vessels participating in the GMDSS. ? Class E: provides minimum facilities for MF and/or HF DSC distress@ urgency and safety as well as routine calling and reception as recommended by IMO MSC/Circ.803 for non-SOLAS vessels participating in the GMDSS. ? Class H: provides minimum facilities for handheld VHF DSC distress@ urgency and safety as well as routine calling and reception as recommended by IMO MSC/Circ.803 for non-SOLAS vessels participating in the GMDSS. ? Class M: provides minimum facilities for VHF Man Overboard devices as defined in Recommendation ITU-R M.493-15. NOTE 1: Class A equipment may support the optional semi-automatic/automatic service in accordance with Recommendations ITU-R M.689-3@ M.1082-1 and M.493-15@ tables A1-4.10.1 and A1-4.10.2 and are encouraged to do so. NOTE 2: Class D and Class E equipment may also support the optional semi-automatic/automatic service.
